I know there are now Planeswalker Points and I follow that, but I was wondering when (or if) they are retiring the DCI Rating? I heard somewhere that would be December 31st, 2011, but I wanted confirmation.
I'm curious since although there are PWP, I personally still follow my DCI Rating since it still updates and it gives me a better representation of my skill level since it is a zero-sum game.
Now I don't want to debate the validity of one over the other. I am simply stating that I like that it still updates (even if it has no use) and was wondering if anyone knew when it was going to officially be retired (if at all)? I can't find it in the Official Announcement so I hope that means it'll update indefinitely.
As you've stated, probably Dec 31. It still has use, as it's still used to award byes for Grand Prixs.
Yeah I heard it from somewhere, but it wasn't official. Does anyone know of an "official" response? It makes the most sense to retire it at the end of the year, but just curious.
I'd prefer they kept it going, if at the very least so players can still look it up, but not actually use it for byes, etc. as they now have PWP.
DCI rating isn't zero sum. players dont gain and lose points from winning and losing on a one-to-one basis. the points lost and gained depend heavily on the rating of your opponent. a low ranked player will, on average, play against players ranked above them more frequently than those ranked below them and therefore will gain many points per win and lose few points per loss. conversely, a high ranked player will, on average, played against players ranked below them more frequently than those ranked above them and therefore will gain few points per win and lose many points per loss.
this has created the trend where high ranked players tend to never play against the general population to preserve their rating. similarly low ranked players tend to play against the general population frequently and they tend to rapidly gain rating, to a certain point.
the net total trend is that there is points inflation. low ranked players tend to inflate towards middle rank within a short period of active playing. the only way to preserve high ranking is to go on fabulous winning streaks or to simply refuse to play against players who are not already similarly ranked to yourself.

this is not in any way a zero sum system.
First off, I specifically said I did not intend this thread to be a debate on whether the new or old system was better or worse. There's plenty of threads spanning hundreds of pages regarding this point that I think it's beating a dead horse.
With that said, if you really want to argue about something as trivial as definitions, it is a zero sum game. The loser loses X points and the winner gains exactly X points. Currently, if a higher ranked player beats a lower ranked player, they gain X rating (where X is a value less than the k-value). If the lower ranked player beats the higher ranked player, they gain X rating (where X is a value greater than the k-value). The loser of both instances lose exactly X rating as well. There is a net result of zero points being "created."
"In game theory and economic theory, a zero-sum game is a mathematical representation of a situation in which a participant's gain (or loss) of utility is exactly balanced by the losses (or gains) of the utility of other participant(s)."
You're right in that it's more risky for a highly rated player to play against lower rated players, but that doesn't mean it's still not zero sum. The loss of rating (X) is just high for said player and for the opponent, the gain (also X) is very high. It results in sitting on your rating, but again, that doesn't mean it is not a zero sum game. It just means highly rated players have less to gain.
With that out of the way, I'd appreciate staying on topic since I am simply asking a fairly straightforward question. If you disagree with the past DCI rating, I suggest you reply in one of the previous threads. I'm sure you'll find plenty of opinions.

I suggest reading the first line of the Wikipedia entry:
